The present invention relates to a platform for industrial installations, in particular for high-pressure descalers, emergency shears, and pendulum shears in rolling mill trains or the like with optionally bundled supply, discharge, and/or distribution conduits which in operational position, are connectable with fixed conduits of a respective machines.
Supply of the machine with hydraulic fluid, lubricating and cooling media, electrical energy, and control signals is effected through tubes and conduits over the foundation or in foundation trenches. In addition, e.g., ventilation units are arranged in a decentralized manner on the foundation, on separate consoles or on the floor. This arrangement leads to a large number of tubular conduits extending to a machine for which a large number of interfaces foundation/machine is necessary. Moreover, these interfaces are individually secured, arranged and, as a rule, are not transferable from installation to installation. Upon changes in the region of the machine, an installation-specific arrangement of lines for separate operational sites is required. Somewhat free-lying tubular conduits make access to the operational sites difficult. In addition, the free-lying tubular conduits are laid out randomly and also make access to different areas of a site between the conduits more difficult. The consoles of motors for driving rolls or the like, distribution blocks for high-pressure descaling are separately arranged on the foundation and anchored thereto. The tubing should inevitably be led around such consoles.
The media conduits are arranged in individual cases in so-called foundation channels. Waste water can penetrate in the foundation channels and cause accumulation of dirt and mud which with time can form a thick solid layer.
A drawback consists also in that installation features to be installed on the site such as, e.g., stands for measurement equipment, other supports and the like can be secured between the tubes only with large expenses or, because of lack of space, should be installed at a large distance.
European patent EP 1 100 634 B1 discloses an arrangement of supply, discharge and distribution conduits of a distribution network for fluid operational media such as, e.g., lubricating and cooling media, and for fluid hydraulic pressure media for servo mechanisms or drives of rolling mill stands provided with a column. At that, modules mountable on a stand are used, and tubular conduits are combined in groups. This arrangement is advantageous for a rolling mill stand, however, the principle cannot be used without further modification in other machines.
The object of the invention is to provide on a respective site a central installation for connecting media and power lines which can be monitored and easily controlled.
The set object is achieved according to the invention in that an arrangement of the platform in an immediate proximity with predetermined distance, lateral position and height with regard to a connectable, machine is carried out, and in that control units, devices, drives and drive consoles, distribution blocks, valve units, control elements and the like are distributed over a horizontal, polygonal platform foundation surface according to their functions with regard to the machine. The advantage of this arrangement consists in that: The expenses of equipping a site with tubings is reduced. The access to tube junctions, servo mechanisms and drives is improved. As a result of arrangement of control elements at a central location, the service works and control possibilities are favorably influenced. The hydraulic tubing in the foundation is noticeably reduced. The platform provides a large surface for a central arrangement of auxiliary components. In addition, definite and standardized interfaces are provided.
Tube connections have a better arrangement and are unambiguously associated with consumers.
According to an advantageous embodiment, there is provided a frame construction with adjusting feet and foundation fastening elements and in which media conduits are set in.
Other features consist in that tubular conduits for media, such as, e.g., hydraulic fluid, water, high-pressure water, air, lubricant and electrical conductors are provided ends of which project past the platform foundation surface by a connection section. The connections are located somewhat outside and are easily accessible.
The construction of the platform can be improved by providing supports for consoles, the distribution block, valve units, and the like.
Respective connection sections are formed as flange, welding or coupling connections.
It is further proposed to arrange, within the platform foundation surface, grids for discharge of liquids or cover sheets for accessibility. If necessary, it can thereby be prevented that spray water could flow through the platform.
A further advantage for the assembly of the platform consists in that it can be transported in an assembled condition as a unit.
The drawings show embodiments of the invention which will be described in detail below.
